MIT Instrument Finds Surprises at Solar System’s Edge

The Voyager 2 spacecraft’s Plasma Science instrument, developed at MIT in the 1970s, has turned up surprising revelations about the boundary zone that marks the edge of the sun’s influence in space. The unexpected findings emerged in the last few weeks as the spacecraft traversed the termination shockwave formed when the flow of particles constantly streaming out from the sun–the solar wind–slams into the surrounding thin gas that fills the space between stars.
